In the process of two-stage hydrogenation from bio-oil to jet fuel, the selective cracking and isomerization of long-chain alkanes is the key step. The n-C16 was used as the model reactant to produce jet fuel and the supported metal-acid bifunctional HPA/MCM-41 catalyst was prepared. The acid strength and amount of the catalyst could be modified by adjusting the type (HPW, HSiW, HPMo) and loading of HPA. The highest yield of jet fuel (≈ 20 wt.%) was obtained over Pt/40 wt.% HPMo/MCM-41 (WHSV = 1 h⁻¹), which possessed more B acid sites but few strong acid sites. Besides, it possesses a higher yield than the previous work and favorable catalytic stability of 100 h. It was further explored that the reaction path net of hydrocracking and isomerization of n-C16 was a cascade reaction from n-C16 to single-branched isomer, further to multi-branched isomer and then to the cracking product.

在从生物油到喷气燃料的两步加氢过程中，长链烷烃的选择性裂解和异构化是关键步骤。以n-C16为模型反应物，生产喷气燃料，制备了负载型金属-酸双官能HPA / MCM-41催化剂。可以通过调节HPA的类型（HPW，HSiW，HPMo）和负载量来改变催化剂的酸强度和用量。在Pt / 40 wt。％HPMo / MCM-41（WHSV = 1 h ^-1）上可获得最高的喷气燃料收率（≈20 wt。％）），它具有更多的B酸位点，但几乎没有强酸位点。此外，它具有比以前的工作更高的产率和100小时的有利催化稳定性。进一步探讨了n-C16加氢裂化和异构化的反应路径网是从n-C16到单支链异构体，再到多支链异构体再到裂化产物的级联反应。
